The Mosaic Company is a leading producer and marketer of concentrated phosphate and potash crop nutrients and a single source supplier of phosphate and potash based crop nutrients and animal feed ingredients. It mines phosphate rock in Florida, Brazil and Peru and processes the rock into phosphoric acid to create finished fertilizer products. The company also extracts potash from mines in Saskatchewan and New Mexico and manufactures products such as muriate of potash and specialty blends. It serves customers in approximately 40 countries and operates production, blending and distribution facilities in the United States, Brazil, Peru and Canada.
The Mosaic Company generates revenue mainly from the sale of phosphate based crop nutrients including diammonium phosphate, monoammonium phosphate and MicroEssentials, from potash products such as muriate of potash and specialty fertilizer blends, and from phosphate and potash based animal feed ingredients sold under brands like Biofos, Nexfos and Foscálcio. The Mosaic Fertilizantes segment contributes revenue through the production and sale of phosphate and potash based crop nutrients and animal feed ingredients in Brazil, as well as through nutrient blending and distribution activities in Paraguay. Additionally, the company's China and India distribution businesses generate revenue by marketing imported phosphate and potash products to wholesalers, cooperatives and farmers in Asia.
The company operates through the following reportable business segments: Phosphate, Potash and Mosaic Fertilizantes.
• Phosphate: This segment mines phosphate rock in Florida, Brazil and Peru, processes the rock into phosphoric acid and produces concentrated phosphate crop nutrients such as diammonium phosphate, monoammonium phosphate and MicroEssentials, and manufactures phosphate based animal feed ingredients under brands like Biofos and Nexfos. In 2025 the segment produced approximately 6.3 million tonnes of concentrated phosphate crop nutrients and accounted for about 72% of estimated North American annual production.
• Potash: This segment extracts potash from mines in Saskatchewan and New Mexico, produces muriate of potash and specialty products such as double sulfate of potash magnesia, and markets these goods globally for fertilizer, industrial and limited animal feed use. In 2025 the segment generated 8.8 million tonnes of potash product, representing approximately 12% of estimated world annual production and about 34% of estimated North American annual production.
• Mosaic Fertilizantes: This segment operates five phosphate mines and four chemical plants in Brazil, produces phosphate and potash based crop nutrients and animal feed ingredients, blends nutrients in Brazil and Paraguay, and distributes products through a network of sales offices, blending facilities, ports and warehouses in South America. In 2025 the segment sold approximately 9.0 million tonnes of crop nutrient products and accounted for about 17% of fertilizer shipments in Brazil.
The Mosaic Company holds a leading position in the global crop nutrient industry as one of the top producers of concentrated phosphate and potash. It is the second largest integrated phosphate producer worldwide and the largest fertilizer producer and distributor in Brazil. The company ranks among the top four global potash producers and benefits from a vertically integrated model that controls mining, processing and distribution. Its scale provides cost advantages, while products such as MicroEssentials differentiate its offering in North and South American markets. The company's extensive logistics network, including owned ports, warehouses and transportation assets, enables it to serve customers in about 40 countries efficiently. Additionally, long term supply agreements for key inputs such as sulfur and ammonia help stabilize production costs and support competitive pricing.
The company's customers include manufacturers of crop nutrients, wholesale distributors, retail chains, cooperatives and farmers who purchase phosphate and potash based fertilizers for agricultural use. It also supplies animal feed ingredients to poultry and livestock producers, as well as to aquaculture operations in select regions. The business serves a diverse base across North America, South America and Asia, with a notable presence in the United States, Brazil, China and India.

Investment Thesis
▲ Bull case
The Mosaic Company is positioned to capitalize on a structural global phosphate shortage that is creating a multi-year tailwind for pricing power and market share gains, as the current supply constraints are not merely cyclical but rooted in persistent geopolitical disruptions affecting nearly half of global phosphate raw material flows from the Middle East and Black Sea regions. Management's admission that "there is not going to be enough phosphate to meet global demand" underscores a fundamental imbalance where demand destruction from farmer affordability concerns in the Americas is being more than offset by strong, policy-supported demand in Asia—particularly India, where government commitments to sustain phosphate imports at current prices provide a reliable demand floor. This dynamic allows Mosaic to leverage its diversified sourcing advantages, including 80% of U.S. ammonia needs from internal production and advantaged Gulf sulfur supply chains, to maintain production flexibility while competitors face of spot market volatility, enabling it to capture premium pricing in international markets without sacrificing domestic market access when conditions normalize. The company's ability to shift capital toward higher-margin opportunities, evidenced by the divestment of underperforming assets like the Carlsbad potash mine and the idling of SSP production in Brazil, is not merely defensive but strategic—freeing up capital for high-return investments in Mosaic Biosciences, which is expected to double revenues in 2026 through 8-10 new product launches, and rare earth element extraction from phosphogypsum stacks, a long-term opportunity that transforms a waste byproduct into a high-value revenue stream with minimal incremental CapEx. Furthermore, the disciplined reduction of 2026 CapEx guidance by $250 million to $1.25 billion, coupled with workforce reductions generating $50 million in annualized savings, is strengthening the balance sheet without compromising long-term production targets, positioning Mosaic to deploy capital aggressively when sulfur and ammonia prices normalize—likely driven by resolving Strait of Hormuz disruptions—thereby unlocking significant operating leverage as stripped margins recover from current depressed levels to historical norms, with the potential for substantial earnings upside as the company's improved asset reliability (three of four U.S. phosphate facilities operating at or above 80% phosphoric acid rates) combines with pent-up demand from prolonged underapplication in key markets like Brazil and the U.S., where agronomic consequences will eventually force nutrient replenishment cycles.

The Mosaic Company faces significant near-term headwinds that the market may be underestimating, particularly the unsustainable margin compression driven by record-high marginal sulfur costs of $1,200 per ton and ammonia costs near $800 per ton, which, when applied to current production economics, result in marginal stripping margins below variable cost—meaning each additional ton produced at current input prices generates a loss, a reality management implicitly acknowledged when discussing how curtailments are necessary to avoid operating at a loss despite strong international pricing. This dynamic is exacerbated by the company's continued reliance on spot markets for 20% of ammonia and a portion of sulfur needs, leaving it vulnerable to further price spikes if geopolitical tensions in the Persian Gulf persist or intensify, potentially pushing working capital requirements higher than anticipated despite production cuts, as higher raw material costs inflate inventory valuations even as volumes decline, creating a scenario where cash flow generation could be delayed or diminished beyond current guidance. In Brazil, the decision to idle SSP production at Araxá and Patrocínio—while framed as a long-overdue strategic move—masks deeper structural weaknesses, as the facility's historically poor returns due to import competition in SSP suggest that the underlying asset base may lack competitive scale or cost advantages, and the anticipated $20-30 million in annual maintenance CapEx savings may be offset by ongoing ARO liabilities and potential environmental remediation costs tied to gypsum stacks, especially if the company pursues alternative uses like niobium extraction at Patrocínio without clear near-term monetization paths. The potash business, often cited as a stabilizing force, shows signs of underlying fragility, with flat FOB mine price guidance at $260 per ton despite rising spot prices in Brazil and strong Canpotex commitments, indicating that Mosaic is not benefiting from favorable pricing dynamics due to its reliance on long-term contracts that lag spot markets, while the exclusion of K-Mag from guidance obscures true volume trends and raises questions about whether the apparent strength in Canpotex shipments is being offset by declining profitability in higher-cost operations like Colonsay, where ramp-up of HydroFloat and optimization projects may fail to deliver promised cost savings if technical challenges or inflationary pressures delay benefits. Finally, while Mosaic Biosciences and rare earth initiatives are presented as long-term growth drivers, they remain early-stage and unproven at scale, with no concrete timelines for meaningful revenue contribution beyond 2026, and the company's continued investment in these ventures risks diverting capital from core phosphate and potash operations at a time when free cash flow is under pressure from working capital buildups driven by elevated raw material costs, potentially worsening leverage ratios if the expected normalization of sulfur and ammonia prices is delayed beyond the current assumption of a near-term resolution in Strait of Hormuz flows.
